Integrated protection functions are designed to prevent IC destruction under fault conditions described in the data sheet. Fault
conditions are considered as "outside" normal operating range. Protection functions are not designed for continuous repetitive
operation.
10)
Requires 150 Ω resistor in GND connection. The reverse load current through the intrinsic drain-source diode has to be limited by
the connected load. Note that the power dissipation is higher compared to normal operating conditions due to the voltage drop
across the intrinsic drain-source diode. The temperature protection is not active during reverse current operation! Input and Status
currents have to be limited (see max. ratings page 2 and circuit page 7).
11)
External pull up resistor required for open load detection in off state.
